Malaysia's primeval and unexplored rainforests offer intrepid trekkers great opportunities to observe tropical flora and fauna.  The wilds of Malaysia overflow with fantastic plant and animal diversity that fulfill the competitive conditions of the ecosystem.  Many species are exotic, rare or even endemic to the particular region and are protected.  Endau-Rompin in Johor is a rare milieu of lowland and mountain forests which is home to the largest population of endangered animals in the country.  The Sumatran Rhinoceros, tigers and elephants are among the protected species in Endau-Rompin.

Generally, most rainforest animals are shy or camouflage themselves to avoid predators or to hunt.  Bumbun or tower hides and canopy walks, such as Taman Negara aid those searching to spot the inhabitants. Take the time to spot the many insects and butterflies flitting about in the forests of Peninsula Malaysia.  Marvel at the pendulous nose of the proboscis monkeys found at Sukau in Sabah and Bako in Sarawak. 

• Find out about the trail and surroundings, be sure that you have enough time to complete the entire route before darkness falls.  Do not stray off the path to chase after animals.

• Use good judgment regarding the fitness level required for the trek, and know your physical limits.

• Always inform the park officials or let someone know of your plans and destination for the day, especially if going alone.

• Take plenty of water and pack a few easy to eat snacks to keep energy level up.  Unless trekking with a local guide, it is not advisable to eat jungle fruit or drink from any water source.

• In the highlands try to trek on the ridge tops to save energy traversing the steep sloped and to catch a cool breeze.

• Be quiet as possible to avoid scaring any wildlife.  Getting an early start during the dawn provides the best chance to sight animals seeking food and the warmth ot the early morning sun.

• Wear thin, loose, preferably cotton clothing to remain comfortable.

• Cover arms and legs with long trousers and long-sleeved shirts to ward off mosquitoes and to provide protection against thorny plants.

• Wear leech socks or long socks to prevent leeches from finding an entry way.

• Choose sturdy footwear with proper ankle support and good traction.

• Be prepared for sudden rain showers by carrying a poncho that wraps over both body and your carrying pack to keep everything dry.

• A wide brimmed hat helps to shade a trekker from the heat of the tropical sun.
